you wanna see some badass shit from the early 20th century?? The Lumière brothers created the first full color photograph… in fucking 1903! So these dudes dyed potatoes (in red, blue, and green), mashed them down into just pure fuckin’ starch, and used these dyed potato starches as filters to block out/let in certain wavelengths of light. They coated one side of a glass plate with the starches and sensitized the other side with a mixture of gelatin and light sensitive materials (silver nitrate) and loaded these plates in their cameras.. This is a really simple explanation of the process and I may have missed some things
